The Dutch National Institute for Public Health and the Environment in The Netherlands concludes that some adjustments are needed in the European chemicals legislation REACH to assess and control the risks of nanomaterials.
Chemical Nanotechnology Talks (CNT) is an event for international participants, stressing chemical nanotechnology. Every year there is a focus on a particular theme. This year's focus, on January 26-27 in Frankfurt/Germany lies on 'Green Nano: Challenges of Sustainability' including themes like resources, energy and environment.
According to the foundations of quantum mechanics, two different given paths for quantum particles may interfere. Such a so-called 'double-slit' scenario is put forward devoid of material constituents, consisting instead entirely of light.
By combining several advanced device concepts, Yukio Kawano and colleagues of the RIKEN Advanced Science Institute, Wako, have succeeded in building a highly sensitive THz detector that is capable of sensing just a handful of THz photons at a time.
Researchers in Berlin analyze the movement of those microscopically small organisms in aqueous environments. Following their example, tiny machines with the aptitude to work inside the human body could be built.
A project to expand production of units for applying modified coatings of a single nanometer thickness on materials and goods with the help of a plasma magnetron discharge has won approval from the Supervisory Council of RUSNANO.
The precious metal gold is the material of choice for many technical applications because it does not corrode - and because it also has interesting electrical, magnetic, and optical properties. In these applications, it is extremely important that the surface of the gold be completely clean and smooth. However, conventional processes not only 'polish' away the undesirable irregularities, but also attack the gold surface.
